September skies promise a mix of eclipses, planets, and seasonal change. From a total lunar eclipse to Saturn shining at its brightest, skywatchers will have plenty to look forward to this month.

Total Lunar Eclipse Across Continents
On 7 September, a total lunar eclipse will be visible across Europe, Africa, Asia, Australia, and New Zealand. It marks the second total lunar eclipse of 2025, with the next not due until March 2026.

The event coincides with the Corn Moon, a traditional name for the September full moon. Farmers once used this period to gather crops, especially corn, across the Northern Hemisphere.

Partial Solar Eclipse Over Pacific
A partial solar eclipse arrives on 21 September, sweeping across the South Pacific and parts of Antarctica. In New Zealand, observers can catch the event at sunrise on 22 September local time. Experts remind the public never to look directly at the Sun without proper protection.

That same day, the Moon reaches its new phase, leaving darker skies. This will create perfect conditions to view stars and planets without interference.

Saturn at Opposition and Equinox
Also on 21 September, Saturn will be in opposition. This means the ringed planet will be directly opposite the Sun from Earth, making it visible from sunset until sunrise. Astronomers say the gas giant will shine brighter than usual.

Finally, the September equinox occurs on 22 September, marking the official arrival of autumn in the Northern Hemisphere. Numerous cultures see this time as a moment of balance and seasonal change.
